“…First, they indicate that TPP behavior will vary among potato varieties. As it is known that susceptibility varies among potato varieties (Munyaneza et al 2011), this is not an unexpected Þnding. However, as TPPs can be migratory, populations sometimes expand after invading a Þeld , Swisher et al 2013, and planting time can inßuence disease severity , Munyaneza et al 2012.…”

The ecological theory on host plant choice by herbivores suggests that mothers should choose plants that will maximize their offspring's success. In annual host plants, physiology (and therefore host suitability) is sometimes influenced by maturity and growth stage, which may influence female choice. Potato plants were grown under greenhouse conditions and used in choice and no-choice bioassays to determine the effect of plant maturity and variety on oviposition and number of stylet sheaths (which approximate stylet insertions) by tomato/potato psyllids. No-choice bioassays suggested that maturity (time since planting) did not influence oviposition behavior, but oviposition varied significantly among potato plant varieties. There was a significant effect of both maturity and variety on the number of stylet sheaths, which peak toward the middle of the growing season. We also examined tomato/potato psyllid responses to plants grown in a commercial field and again found no effect on oviposition but differences in stylet sheaths. The results suggest that differential susceptibility to zebra chip disease may be associated with unequal feeding rates. Future studies should examine whether the maturity of plants influences larval fitness. Finally, potato variety has an influence on both oviposition and "probing," and has implications for management strategies and the development of resistant potato varieties.

“…Berry et al (2011) reported that exposure of growing potato plants to Lso-free B. cockerelli at different densities and for different periods of time under controlled field conditions did not have a major influence on potato yield. Munyaneza et al (2011) reported yield losses due to B. cockerelli and ZC damage ranging from 43% to 93% in several commercial potato varieties under controlled field cage conditions in Texas and Washington. From 2009 to 2011, estimates of yield loss due to ZC and B. cockerelli in the southwestern and central United States ranged from 0.5% to 75% (Guenthner et al 2011).…”

“…And this disease has been documented on carrot in North Europe and the Mediterranean Region (Munyaneza 2010(Munyaneza , 2012Munyaneza et al 2011;Alfaro-Fernández et al 2012), and on celery crops in Spain (EPPO 2014). ZC is characterised by symptoms that develop in potato tubers, which consist of collapsed stolons, browning of vascular tissue, concomitant with necrotic flecking of internal tissues and streaking of the medullary ray tissues, all of which can affect the entire tuber.…”

“…Crosslin et al (2010) reported a spread of ZC across geographic regions by dispersing B. cockerelli which helped maintain the bacterium in these regions during the insect's overwintering period. Munyaneza et al (2011) reported yield losses due to B. cockerelli and ZC damage ranging from 43% to 93% in several commercial potato varieties under controlled field cage conditions in Texas and Washington State. Effective monitoring and control of B. cockerelli are essential strategies in order to better manage ZC in potatoes.…”

Gao F., Zhao Z.H., Jifon J., Liu T.-X. (2016): Impact of potato psyllid density and timing of infestation on Zebra chip disease expression in potato plants. Plant Protect. Sci., 52: 262-269.The impact of vector density and timing of infestation on potato were investigated. Healthy potato plants at different growth stages (4, 5, and 7 weeks after germination) were exposed separately to four different B. cockerelli densities (0, 5, 20, and 40 psyllids per cage) in field cages and Zebra chip (ZC) symptoms, leaf photosynthetic rates, tuber yield, and total nonstructural carbohydrate accumulation in leaves and tubers of healthy and B. cockerelli-infested plants were monitored. Potato psyllid nymph and egg populations reached a seasonal peak at 6 weeks after the exposure to insect. Younger plants at 4-week growth stage after germination were more susceptible to B. cockerelli infestation and ZC expression than older plants. As few as five B. cockerelli adults were enough to transmit the ZC pathogen and cause ZC expression both in foliage and tuber. At the density of 20 psyllids per cage, more than 50% of plants showed ZC symptoms in tubers. Furthermore, B. cockerelli infestation reduced leaf photosynthesis rates (P n ), resulting in less starch and more reducing sugars in tubers, and hence reduced tuber weight and yield, especially when psyllid infestation occurred at the early growth stages. The results indicate that early B. cockerelli infestation of younger plants was associated with more severe ZC expression in both foliage and tubers, leading to earlier dead plants. The data suggest that strategies for controlling B. cockerelli during early potato crop development could thus lessen the severity of ZC development.
